The weightedmean of the random variable is the expected value.
随机变量的加权平均值是期望值。

When fusing several outputs of similar sensors, we often use the weightedmean method. The weight has great influence on the fusing result.
对多个同类传感器的输出数据进行融合时多采用加权平均法，权的分配对融合效果的影响十分明显。

According to the value of weightedmean roughness the priority of different characteristic information can be distinguished, so the proposed method possesses strong tolerant ability.
